| Sensory memory. Capacity, coding, and duration. | Capacity: Potentially unlimited
Coding: Raw (no encoding)
Duration:1/4sec-4sec |
| Short term memory. Capacity coding and duration | Capacity: 5-9
Coding: Acoustic
Duration: 18s |
| Long term memory. capacity coding and duration | Capacity: Potentially unlimited
Coding: Semantic
Duration: Potentially unlimited |
| How do you lose Sensory, short term, and long term memory | Sensory: Lack of attention, decay
STM:Displacement, decay
LTM:Interferance, decay, retrieval failure |
| How do memories move into the different stages | Environment--> sensory --> attention --> Elaborate rehearsal --> long term memory |
| Who was John B Watson | American founder of the behaviorist approach, did the Little Albert experiment |
| What did sperling do | Multi store model, studied capacity of sensory register using 3 rows of letters and tone to signify which one to recall, they increased the time between seeing the letters and the tones to see how long the capacity is |
| What did Jacobs do | Multi store model capacity of STM. 443 female participants asked to read digits and letters and recall them in the correct order. The length of the digits and letters increased every time, the amount of characters recalled was the capacity of sensory memory, which is 5-9 |
| What did Peterson and Peterson do | Multi store model duration of STM
Trigram followed by distractor task which lasted an increasing amount of time. The amount of time that still allowed people to recall the trigram was the duration of short term memory, which is 18sec |
| what did tulving do | Used brain scans to determine where different LTM are stored. Episodic in temporal lobe, semantic in hippocampus, and procedural in cerebellum |
| what did bahrick do | multi store model duration of LTM. Asked people to recall names of people in their graduating yearbook. Duration was tested by asking people of different ages. Duration was potentially lifelong |
| What did baddeley do | Muti store model coding of STM and LTM. Showing participants 4 sets of words that were either acoustically similar/dissimilar, and semantically similar/dissimilar. They had to recall the lists right away (STM) and then 20 mins later (LTM). People got the most mistakes on acoustically similar words for STM, therefore STM codes acoustically. People got the most mistakes on semantically similar words in LTM, therefore LTM codes semantically. |
| What is HM case study | HM had an operation to remove his hippocampus to cure this epilepsy. This worked, but he lost the ability to lo learn new episodic or semantic memories, he could still learn new procedural memories |
